Abstract

591 strains of myxobacteria that grew on cellulose as a sole carbon source were isolated from soils collected from various locations in Korea. Morphological characteristics such as the shape of cells, colonies and fruiting bodies and 16S rRNA sequences of the isolates suggested that all the isolates are Sorangium cellulosum. An antifungal assay has indicated that at least 20 strains among the 114 isolates tested produce antifungal substances inhibiting growth of Candida albicans.

한국의 여러 지역에서 채취한 토양으로부터 셀룰로오스를 유일한 탄소원으로 이용하여 자라는 591균주의 점액 세균을 순수 분리하였다. 세포, 집락, 그리고 자실체의 모양과 같은 형태적인 특징과 16S rRNA 염기서열은 이들 균주들이 모두 Sorangium cellulosum임을 나타내었다. 그리고 생리활성조사는 114균주 중 최소한 20균주가 Candida albicans의 성장을 저해하는 항진균물질을 생산함을 보여주었다.
